SUSPENSION HGOK.

Application filed' February 4, 1926.

The suspension. hook of the present invcn tion is in the nature of a self-lubricating device adapted for a wide range of utility in supportingr various types of freely swinging elements, but finds its preferred embodiment in a noiseless hanger for porch swings and the like.

An object of the present invention is to provide a suspension hooi: so constructed that thepivot bearings for the hook are ini-` mersed in a bath of lubricating liquid.

A; further object of the invention is to provide a two part device of this character' *which includes a combined oil reservoir and bearing' box, and a hanger hook removably mounted in said box, both of the parts being of fsimple, practical construction and capable of ready attachment to any suitable supporting means.

Further objects of the invention are to rovide a device of this character which will be rugged, durable and efficient in use, and `which may be manufactured With compara tive economy.

Vith the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements 'of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a top plan View of-a suspension hook and its supporting bearing box.

Fig. 2 is a transverse section therethrough on the line 2 2 of Fig. 1, but showingJ the box attached to a suitable support.

Fig. 8 is a side elevational view of the device shown in Fig. 1.

Fig. 4 is a transverse sectional View on the line 4-4 of Fig. 1.

In the drawings I have used the reference character 10 tol designate a ceiling, cross beam or other suitable support for the suspension hook. The device includes a coinbined oil reservoir and bearing box of open topped construction which comprises side Walls 11 and a bottom Wall 12. Communieating with an opening; 13 in the bottonof the box, are a pair of transverse interior partition vvalls 14 Which coact with the side Walls of the box to define a pair of reservoir chambers, at the opposite sides of a central elongated opening.

The side Walls 11 neartheirupper ends serial No. secas.

are outwardly flanged as at 15 and provide a series of laterally extending apertured ca rs 16 through which screws 17 or other appropriate securing devices are adapted to be passed for mounting the bea: on the lunder face of the support 10. Strengthening -the lianged construction and protecting the screw heads, are a series of v epending Webs 1S preferably arranged closely adjacent the screw holes in the ears 1G.

The reservoirs defined by the side Walls 1l, inner Walls 111 and bottom Wall 12 are adapted to receive lubricating oil, the oil line being;- below the inlet openings 19 in the side Walls of the box. These inlet openings commi nicate with oppositely disposed vertical bearine; grooves 20 in the interior of the box 'which receive horizontally disposed trunnion portions 21 at the extremities of the legs of an inverted U-shaped hanger 22, the intermediate portion of which is integral with the depending shank of a hook 24. The legs 25 of the inverted tl-shaped element are of suilicient length so .that the intermediate portion 22 thereof is disposed above the tops of the partitions 14. f" The lshank 23 of the hook extends downwardly through the central openingl in the box and the trunnions 21 are confined in the bearing grooves 2O so that the suspension hook 24 rocks about the trunnions as bearings. The curved tops of the partitions 14 provide am )le clearance for rocking movement of the -shaped element on its trunnions. n

Provision of the oil inlet opening 19 permits the reservoirs to be replenished at any time Without removing the box from its support- 10. The manner of use of the device Will be obvious, as any suitable pend ing element may be hungY upon the hook 21. rllhe reservoirs may be filled with oil either before or after the application of the box' to the support, and tne assemblyr of the suspension hanger with. the box simply consists in dropping the trunnions into their guide grooves.

"Various changes and alterations might be made in the generali forni and arrangement lof parts described Without-departing from the invention. Hence I do not ivish to limit myself to the details set forth. but shall. consider myself at liberty to malte such changes and alterations as fairly fall within the spirit and scope of the appended claims.-

claim A suspension device including' an open eri topped bonr adapted to be secured to the under face of a horizontalsupport, sald box including an opening in its bottom and in# ternal vertical partit-ions cooperating with the side Walls of the bor: to define oil reservoirs between the partitions and the Walls on opposite sides of lthe central opening, a swing hook including bearing portions' rock ably mounted in the oil reservoirs, and a shank depending through the opening dcned by the central partitions, the Walls of the reservoirs being rovided with pockets for the reception 'of tie ends of the bearing members.

2, A suspension device including an ope'n topped box adapted to be secured to the nnder face of a horizontal support, said box including an opening in its bottom and intermal vertical partitions cooperating with the side Walls of the box to define oil reservoirs between the partitions and the Walls n .opposite sides of the central opening, a swing hook including bearing portions rockably mounted in the oil reservoirs, and a shank depending through the opening defined by the central partitionsj said hook including an inverted U-shaped element stradrecentie dling the vertical partitions and terminating in laterally disposed trunnions having bearings in the oil reservoirs, the shank of the hook being' rigid with the intermediate portion of said inverted U-shaped member.

3. A suspension device including an open topped box adapted to be secured to the under face of a horizontal support, said 4box including an opening in its bottom and internal vertical partitions cooperating with the side walls of the box to' del-ine oil reservoirs between the partitions and the lWalls on opposite. sides of the central opening, a swing hook including bearing portions rockably mounted in the oil reservoirs, and a shank depending through the opening defined by the central partitions, said hook including an inverted U-shaped element straddling the vertical partitions and terminating in laterally disposed trunnions having bearings in the oil reservoirs, the shank of the hook being rigid With the intermediate portion of said inverted vU-shaped member, said box having vertical bearing grooves in its interior for the reception of the trunnions.
